Python Programming - Defining Source Code Encoding

You can add the following lines at the beginning of your Python source codes to specify the encoding.

#!/usr/bin/python
# -*- coding: <encoding name> -*-

For example, you want to encode your source code in ASCII codes, you can add the following two lines at the beginning of your python source codes.

#!/usr/bin/python
# -*- coding: ascii -*-
